Assemblin acquires Larmerud in Norway

Assemblin has acquired the Norwegian heating and sanitation company Larmerud rørservice AS (“Larmerud”) with 24 employees and annual sales of approximately NOK 41 million. The acquisition strengthens Assemblin’s position in central Østlandet.

Larmerud was established in 2001 but has roots dating back to 1948. The operations are based on Sofiemyr, where a full-range heating and sanitation store is maintained, but are also active in and around Oslo, Follo and Østfold. In addition to operating a full-range heating and sanitation store in Sofiemyr, the company conducts service operations and installation projects for companies and private individuals alike. One of Larmerud’s areas of specialisation is water and sewerage solutions for private homes lacking a municipal water supply.

For Assemblin Norway, which already maintains heating and sanitation operations in Oslo, Sarpsborg and Ski, the acquisition strengthens capacity in a region with a very high level of activity.

“In our acquisition processes, we primarily seek profitable businesses with values and culture similar to ours. We have had a good dialogue with Larmerud throughout the process, and I am convinced that this acquisition will strengthen us in many areas,” says Torkil Skancke Hansen, President and Business Area Manager at Assemblin Norway.

Larmerud has a stable customer portfolio and a well-stocked order backlog.

“We have had talks with several major players, but Assemblin soon became our top choice. We agree on critical issues, such as culture, level of service and attitude. For us, it has been important to be able to maintain the local connection, while securing the future of the business,” says Geir Sparengen, CEO and principal owner of Larmerud.
